As teams try to get out of pool play at the World Cup in Brazil, FIFA has been busy with claims of discrimination, neo-Nazi messages and photos of fans in blackface.

The Germany-Ghana match Saturday was the backdrop for a lot of it.

A man who ran onto the pitch during the match was a neo-Nazi sympathizer, and FIFA is investigating after several pictures of men, appearing to be Germany fans, were posted on social media sites and show the men wearing black-painted faces.

In addition, FIFA's disciplinary panel ruled Monday that an alleged gay slur chant by Mexico fans heard during a June 13 match against Cameroon "is not considered insulting in this specific context."

Meanwhile, Fare - the fans' anti-discrimination network -questions how stadium security did little or nothing about fans in blackface and didn't prevent a neo-Nazi sympathizer from storming the field during Saturday's second half, according to The New York Daily News.

The man who ran onto the pitch had messages written on his chest and back included "HH", signifying Heil Hitler, and "SS," referring to the Nazi paramilitary unit, per multiple reports.

"There would be no other explanation for it," Fare executive director Piara Powar told The Associated Press on Sunday. "The question becomes how does one control an individual fan who chooses to mark his body and jumps on the pitch to propagate his neo-Nazi views."

The man ran onto the pitch in the second half of the 2-2 draw, revealing an email address and telephone number with a Poland international code written on both his chest and back.
